One thing I see frequently around here is people driving with their rear fog light(s) on all the time. I usually see it on Audi's with the single rear fog light that is much brighter than the tail lights. It makes me wonder what these drivers are thinking. Maybe they think it is cool to have their fog lights on all the time, or they are comepletely clueless when they see the buttons on the dash and think one is for the front driver's side fog light, and the other is for the front passenger side fog light. Either way, it is quite annoying driving behind a car with a bright rear fog light when the conditions aren't foggy.
